1.	Which of the following type of directional patterns usually exhibit by erosion-corrosion?(a) Grooves(b) Waves(c) Rounded holes(d) Grooves, waves and rounded holesThis question was addressed to me by my school principal while I was bunking the class.My query is from Eight Forms in chapter Eight Forms of Corrosion of Corrosion Engineering
Answer» Correct option is (d) GROOVES, waves and ROUNDED holes The explanation is: Erosion corrosion results in wear or ABRASION of the surface of the metal. It is CHARACTERIZED in appearance by grooves, gullies, waves, rounded holes, and valleys.
